TFF Pharmaceuticals Announces Program Updates for Voriconazole Inhaled Powder and Tacrolimus Inhaled Powder Clinical Programs

FORT WORTH, Texas, Nov. 01, 2022 (GLOBE NEWSWIRE) -- TFF Pharmaceuticals, Inc. (NASDAQ: TFFP), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative drug products based on its patented Thin Film Freezing (TFF) technology platform, today announced program updates for Voriconazole Inhaled Powder (TFF VORI) and Tacrolimus Inhaled Powder (TFF TAC) clinical programs.

We expect to deliver preliminary patient data from the Phase 2 study of TFF VORI in the first quarter of 2023 and TFF TAC in the second quarter of 2023. These Phase 2 studies are expected to provide safety, tolerability, and efficacy data. The timing of data release has been updated due to several challenges related to staffing shortages, shipping, and global supply chain delays. We continue to work diligently to overcome these challenges.

Specifically, we are working with our CRO to solidify our assigned team as they are working through an integration process following a merger. We have taken a hands-on approach to assist our clinical sites that have managed issues related to staffing shortages within the healthcare system. Additional sites are being added to accelerate enrollment. We have been diligently working with our CRO and regulatory agencies that have also been managing through staffing shortages to obtain country-specific regulatory and ethics study approvals for all clinical sites. We have addressed protracted global supply chain issues that impeded the acquisition of the comparator drug for the TFF VORI trial.


“Clinical trial operations and logistics for much of the pharmaceutical industry, including TFF, continue to be impacted by ongoing staffing shortages and global supply chain constraints, which have subsequently led to challenges in predicting enrollment and data readouts,” said Glenn Mattes, Chief Executive Officer of TFF Pharmaceuticals. “We continue to believe in the value creation of our internal pipeline. As announced today, we believe the positive results from a second patient in our compassionate use program of TFF VORI demonstrate how Thin Film Freezing can be applied to deliver potentially life-saving medicine in a more targeted, safer manner to patients. We are addressing the outstanding issues and have factored their impact into our current guidance for the TFF VORI and TFF TAC programs, and will provide further updates as appropriate.”


TFF Pharmaceuticals’ proprietary Thin Film Freezing (TFF) technology allows for the transformation of both existing compounds and new chemical entities into dry powder formulations exhibiting unique characteristics and benefits. The Thin Film Freezing process is a particle engineering process designed to generate dry powder particles with advantageous properties for inhalation, as well as parenteral, nasal, oral, topical and ocular routes of administration. The process can be used to engineer powders for direct delivery to the site of need, circumventing challenges of systemic administration and leading to improved bioavailability, faster onset of action, and improved safety and efficacy. The ability to deliver therapies directly to the target organ, such as the lung, allows TFF powders to be administered at lower doses compared to oral drugs, reducing unwanted toxicities and side effects. Laboratory data suggests the aerodynamic properties of the powders created by Thin Film Freezing can deliver as much as 75% of the dose to the deep lung. Thin Film Freezing does not introduce heat, shear stress, or other forces that can damage more complex therapeutic components, such as fragile biologics, and instead enables the reformulation of these materials into easily stored and temperature-stable dry powders, making therapeutics and vaccines more accessible for distribution worldwide. The advantages of Thin Film Freezing can be used to enhance traditional delivery or combined to enable next-generation pharmaceutical products.


TFF Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company engaging patented rapid freezing technology to develop and transform medicines into potent dry powder formulations for better efficacy, safety, and stability. The company’s versatile Thin Film Freezing (TFF) technology platform has broad applicability to convert most any drug, including vaccines, small and large molecules, and biologics, into an elegant dry powder highly advantageous for inhalation, with improved absorption so drugs can also be delivered to the eyes, nose and topically to the skin. TFF has two lead drug candidates in the clinic: Voriconazole Inhalation Powder and Tacrolimus Inhalation Powder and continues to expand its pipeline by collaborating with a broad array of pharmaceutical companies, academic institutions, and government partners to revolutionize healthcare around the globe. The TFF Platform is protected by 120+ patents issued or pending in the U.S. and internationally. To learn more about TFF Pharmaceuticals and its product candidates, visit the Company’s website at
